Lips barely touching, I feel the heat of her breath as she breathes out slightly. I back away, she smiles. I'm surprised. I bite my lip and she smiles bigger. Her grin lights up her whole face, and it makes my heart hurt. She's so beautiful. She kissed me. Wow.

"I..." I try to stumble through a word, not even sure what I want to say. She makes my head swim and I think she knows it. Do I do the same to her? I know my cheeks are red. I dip my head. She comes close to me and lightly touches the back of my hand with her fingertips, then trails them up my arm. I shiver and my heart is pounding.

"Just be in this moment with me." She whispers, bringing her lips to mine again. Everything around us is a blur. No sounds. No lights. All I can experience is this and it is overwhelming.

I bring my hands to her neck and stroke gently. I gaze into her brown eyes as she studies my face. She brings her hands to my hips and pulls me close. She wants me to kiss her back.

She whispers in my ear as she takes my hands and places them around her waist. "I want you to."

Her eyes are haunting me now. The way she looked at me that day. The need in her face. Her lips so tender and sweet. Everything in my life changed the day I met her. I was willing to throw away everything I had worked for, just so we could be together.

It started out as a girl crush. Plain and simple. She was beautiful and funny and smart. God she had a way with patients and families that I envied.

Let's start at the beginning, now that I have your attention.

I was working as an ER nurse in a big inner city trauma center. We were always short staffed and turnover was just the way of the land. I was used to seeing new people come and go, and since I was more seasoned there I was able to train the noobs and orient them to the floor.

Casey was a new grad nurse. Honestly the first time I met her I was nervous. She was too gorgeous to be so sweet. She was short and thin with this smile that lit up absolutely everything around her. She had a way about her that could sway any belligerent drunk into compliance. She touched people on a deeper level and they just wanted to be near her. She was smart, too. She would catch errors and cautiously monitor people because she had those gut feelings that a patient would tank; and they would and she would be there to save the day. She was an excellent nurse and just as good of a person.

It takes a special personality to be a nurse. It takes a really special nurse to work in the emergency room. One minute to the next there is no telling what will walk through the doors. Will it be someone dumping a gun shot wound at the ambulance bay? Will it be a schizophrenic off his meds and unable to help himself? How about a pregnant woman giving birth in the parking lot? The kid that just got hit by a car? All possible, and we are trained for it all. It's not that we aren't scared, it's that we have the ability to be afraid and push forward to help people. We put ourselves aside and help the most vulnerable. We see people on their worst day, and we make it okay.

Casey was special. It was like she could see the future. She read people so well and she relied on her gut. When a doctor would throw out an order that she didn't like she would stand toe to toe with them in her five foot two, I'm so sweet you will listen to me way and let them know she felt that they were wrong. She got her way a lot.

While I oriented her to the unit we talked and ate lunch together and I stumbled through the things I was supposed to. Truth is, she made me nervous. It's like I couldn't look her in the eyes. She was too...perfect I guess. She kept cracking jokes and we laughed and kept it casual, but at that point I was sure she was completely straight and I wouldn't even be on her radar. She did, after all, have a boyfriend she lived with.

One slow day, after working together for a few months Casey asked about my relationships and if I was seeing anyone. It was an innocent enough question and I blew it off as another opportunity to be sarcastic. I don't talk about personal stuff at work. I remember saying something snide about a shower head and her laughing. Then she cleared her throat and said "lucky shower head." And walked away. Yeah, I had to pick my jaw up off the floor. The rest of the shift was a little tense. Awkward.

That night I barely slept. I kept thinking of that comment. I went over it and over it in my head. Was she being coy? Teasing me?

Luckily our shifts were opposite the next week, so I wouldn't be running into her on the floor and and awkwardly trying to dance around my pretty obvious questions. I didn't want to ask them. I didn't want to see her at all. I don't like mixing work and play. Don't get me wrong, I'm no prude. I play hard and I have lots of casual partners. That's the way I like it-casual. I don't believe in monogamy. I want connection and sex, I also want passion and partnership, but I do not want to feel tied to another person. Speaking of tied...yeah I like that too. I don't need some princess from work figuring out my life and spreading rumors, true or not, about me. She's hot, yeah, but not so hot I'm going to risk my career and reputation doing what I love. Fuck that. I'm a great fucking nurse and I save lives. I want to keep doing that forever. Period.

I have a stretch of days off next week and I'm planning a camping trip to the mountains. This beautiful spot right by Echo Lake. It's secluded and I'm looking forward to some quiet time. It's been hard in the ER this last month and I need to recharge. I pack my bags and make sure my kayak is loaded tight on top of my car. I'm just about ready to head out when my phone dings. It's Casey.

"Yo! How ya been, buddy? It's been a while :)" she texts.

"Hi. Just heading camping. Will be out of service for a few days." I reply. Hopefully she gets the hint.

"Sweet! Where?"

"Echo Lake" my reply is short, like I'm hoping this exchange will be.

"Alone?"

"Just me and nature."

"I was heading that way tomorrow for a hike. Want me to stop in and check on you? Gotta make sure you're still alive!" She replied. I know she is lying. I don't want to be impolite but I also don't want to lead her on. Shit I guess it'd be easier to tell her to fuck off in person so she gets it.

"Sure. I'll be at the south side right by the shore, if you can find me." Coy enough. If she shows I can let her know I'm not interested, if not I can enjoy my peace.

"I'll find you :)" the fuck does that mean?

I get to the lake and it's mid afternoon. It's so warm and I take my time setting up camp. This is what life is about. I'd live in a tent by the lake if I could. So beautiful. The tent goes up and I snack on a granola bar while setting up a fire pit and gathering wood. I set a fire and enjoy the still of the night. The bugs. The birds. The wind. The crackle of the fire I made myself. This is my happy place.

I start to write in my journal by the light of the fire. Everything I write starts with Casey or ends with Casey. I imagine myself touching her skin; her stomach so smooth, and I wonder what she looks like when she is sleeping. What would it be like to see her orga- Wait. I can't do this. She is off limits. Get ahold of yourself, Mel.

I retire to my tent and still can't shake her in my mind. I decide to see if some 'release' would help. I slide my hands down and focus my mind on my past experiences. I can't help but see her in flashes; her lips, her smile, oh fuck. I fall asleep fast after that.

The next morning is heavenly. I sit by a new fire and watch the water while snacking on beef jerky. I should fish but I decide that some rest and relaxation is what I need. I change into my bikini and lay by the shore, soaking up some sunshine. The sounds of nature, and lack of sounds of people, are spiritually lifting. I'm finally at peace.

Just then I hear a vehicle coming near. I see a woman on the drivers seat of a Subaru. Wow, she found me. And I'm in a bikini. Great.

I raise my hand to signal I am here (and alive). I'm not sure how she found my spot. It's not exactly on the regular camping maps. Her horn blasts, souring my serenity.

She throws the car in park and whistles, "damn, baby! Goin my way?!" She jokes. I'm embarrassed and start to put a shirt and shorts on. She bubbles over, smiling. She's wearing her dirty blond hair up under a trucker hat, a teal tank top over a pink bikini top, and white shorts. "I like your tattoos!" She says. I smile but don't say anything. "So...anything exciting happening around here?"

"Nope." I smile big. "It's been pretty quiet til now." She kicks a rock at me playfully and pulls a bottle of whisky out from under the front seat.

"Well, up for a drink?" She looks at me with c'mere eyes. God she's cute.

"It's like, four." I retort.

"Mmm..." she takes a swig. "Didn't realize you were such a prude." She looks at me over the bottle.

I lick my lips and step to her, looking her right in the eyes and take the bottle. I take a big drink and say, "didn't realize you were such a lush."

We giggle a bit and head over to the shore. She shucks her tank and shorts to reveal her neon pink bikini against her tight tan skin. Her thighs smooth against the rough rocky shore. I couldn't help but steal a glance here and there. Once again I am overcome by thoughts of kissing her, touching her. Be cool, Mel. She's taken and you don't need drama. She wants me, too. I can feel it. So, what's her game? Why is she here if she has a boyfriend? Is this some straight girl crush? I'm in no mood to be used and tossed aside...or am I? Wait, we work together. Not gonna happen.

"Rub this on me?" I hear her ask. I look over and she is on her belly, top undone, and holding out some sunblock. I bring myself back to reality and take the bottle.

I've had my hands on beautiful women, but there's something about her. Maybe it's because she's a little forbidden. Either way I'm feeling it. I make sure to rub it in good and she smiles while I do. She knows what she is doing.

"Why are you playing with me?" I say. I was never one for games.

"Huh?" She sits up, clasping her top.

"You have a boyfriend, that you live with. You know I'm into girls. I see how you flirt with me. What's your game? Do you just want to flirt or fuck or what cuz I don't fuck co-workers? " Welp that didn't come out as tactful as I would have liked.

She scoffed and half smiled, then looked over to the water.

"Let's play a game." She says as she puts on a flannel shirt over her top and slips into her shorts. Obviously this takes me by surprise. "Ever played 'never have I ever'?"

"Sure." I say. "We each hold up five fingers and take a turn saying something we have never done. If the other person has done that thing they drop a finger. The player that has fingers up once the other has all of theirs down has to do a dare."

"Good. You go first." She says, showing me her palm, all fingers raised.

"Okay, uhh...never have I ever..." this should be easy to win. I've done lots of kinky shit. "Had a threesome." boom! I chug some whisky. It's dusk now and the colors of the mountain sky shine on the lake. Breathtaking.

Casey puts her thumb down and grins.

I laugh and mutter "oh my..." it's her turn.

"Never have I ever gotten a tattoo." Aw she is giving me one. I drop my finger and ready my next response.

"Never have I ever fucked my boss." I say. Casey drops her pinky finger and her head. "What?!"

She laughs and confesses, "Mark, my boyfriend, was my boss when we met. I quit my job when we decided it was serious. That's when I moved to the ER." She was giggling and obviously a little tipsy. "Look at that sunset." She said. All I could see was her, with the falling shadows on her face. Her perfect smile in awe of nature. She smelled so good, like sunscreen and citrus. The smoke of the fire and the crackle of the wood and embers. This was a perfect moment. This was a moment I knew would be in my mind forever. "Mkay. Never have I ever had a one night stand." She says.

I drop a finger and she looks surprised. "I'm not into committing." I say. She smiles and looks like she wants to say something, but hesitates.

I start, "never have I ever had sex in public." And she immediately drops a finger. "Liar!" I scream! She laughs. "Well I need to know this one!"

"I had sex in the bathroom at a Styx concert." She says. "Not my classiest moment." And she giggles more and takes a drink of the whisky. At this point I am starting to feel a little apprehensive about revealing my personal kinks about being tied up. She seems easy going enough, but we still work together. And fuck, she is so sexy. I wish I could just hit it and quit it, like my regular mot-us operandi

"You know what..." I say. "I surrender." I conceded. "I'll take the dare." It was getting darker now and I was thinking maybe the dark would hinder her dare capability.

"Chicken shit!" She said. And she wasn't wrong. "Fine. I dare you to skinny dip in the lake."

Fuck. Well, I did agree to this. I smile big and start shedding my layers, maybe slowly to tease her a little. I look her right in the eyes as my bikini top and bottoms come off and I grin, then run full speed to the water. I scream as the cold hits me but it's exhilarating. I submerge myself and come up for air. As I turn toward the shore I see Casey knee deep in the water-and completely naked. Oh...shit.

She creeps to me. Her hair above water in a messy bun, the darkness surrounding us both and closing in. I see her body slowly engulfed in the dark water. Her waist...her breasts. My heart feels like it will explode any moment.

She gets close to me and I still and shiver. She is an inch from my face.

"You..." she whispers. "You are so irresistible. I can't stop thinking about you."

"Don't get me wrong, I would fuck the shit out of you." I say and it surprises her. "But I'm not into cheating and really not into co-workers."

I push her away and start to head back to the shore.

"It's more complicated than that!" She says loudly.

I'm at the shore, toweled, and dressed when she comes up. I sit by the fire and let it help me come back to reality. Tipsy is no reason to jeopardize my life.

Casey sits down beside me, holding her hands out to warm them.

"I love Mark." She says. "We have a relationship that is a little...different." She goes on. "It's open...to an extent." She confides.

"To an extent?" I say. Now I'm curious.

"I can be with other people. He just...likes to watch." She says.

My absolute befuddlement cannot be disguised.

She continues. "He's amazing. He loves me and he is sensitive and loving. He has never forced me into anything. This was my idea initially. I told him I couldn't be with just one person. We aren't so different, me and you." Her voice lowers. "I can't be with just one person. But with him, he sees me and he is willing to accept it." She keeps going. "I don't want a long term monogamous relationship. I just want an agreement that this is okay with you and we can keep it casual."

Well, it sounds right to me. I'm not into committing and this is sex without that. Almost perfect. I know I'm missing something.

"What's in it for him?" I ask.

"He likes to watch. That's it." She says without hesitation.

"And if you and I were alone..." I ask.

"That's cheating." She says matter of factly. "Unless it's okayed prior."

"You really love him." I say. Realizing this is a different kind of situation.

"I do. He's real and kind and he loves and accepts me." She dips her head. "That's hard to find. I love him very much." She says lower.

"I..." I am honestly not sure where I stand with this. This isn't something that has ever crossed into my radar. "I don't know how to feel." I say.

"That's fine." She says. "Take your time. I want you to be comfortable." Her sincerity is putting me a little off guard.

"If I say no?" I ask.

"That's totally okay! I ask that you please don't talk about this to anyone at work. Honestly I've never done this with someone I work so closely with, so this is uncharted for me, too." She says, her head low.

"I'm not some experiment." I say, defensively.

"I never felt that way! I...I like you. You are sexy and fun and dangerous. I love Mark. I want him forever. I feel a real attraction to you, like this was meant to be." She said earnestly.

"You've done this before?" I ask.

"I've had sex with other people with Mark." She said. "But I've never had a relationship outside what Mark and I have. That's...that's what I think is different here. I want you so badly. I don't want my relationship with Mark to change. I want to experience this with you. And him." She says, Almost ashamed.

"I'm not sure I can do that. I just don't know if I'm made that way" I say. This is all a bit much.

"That's okay. I respect that" She says, honesty on her face. "But I'm a little tipsy. Can I just sleep here tonight? I'll head out in the morning. No strings attached. Scouts honor." She says, crossing her fingers.

"Okay. Of course." I say. She situated herself inside my tent while I get the rest of the camp ready for sleep. All this new information is running through my head. Damn. What would that be like? Am I expected to have sex with Mark? I don't even know him. What the hell did she think I would say? Hmmm...I wonder what it would be like...wait...no! Ew! God, this girl has me twisted. Seeing her naked was a tease. Now my brain isn't working and my vagina is working overtime.

When I can't keep my eyes open and it's too cold to stay outside I decide it's time to retire to the tent...beside Casey.

I unzip the door and slip inside. I slide under the cover of the sleeping bag and breathe a sigh of relief. Casey is sleeping soundly. Her face, so peaceful, and her hand right beside her lips. God, she's beautiful.

I drift off to sleep thinking of her. I dream sweet dreams of hearing Casey moan, hearing her say my name. I blink open my eyes and it's still dark. I hear Casey, whispering.

"Yes, baby." Is that her?!

"Right there." Yep. I'm not dreaming. That's her. Oh, my. What do I do? I decide to breathe hard and shift around, so she knows I'm not fully asleep, but still probably not paying attention to her.

She stills for a moment. Then I hear, "Mel?"

"Mmm?" I muster with my back to her. I don't want to embarrass her.

"I know you hear me." She says.

I decide to drop the act and turn over, facing her.

"I'm not into cheating either. I won't. But, I think we both know what this is." She says, staring into my eyes.

I pull my face up to kiss her but she pulls away. Wait...what does she want?

She stares at me, studying my face. Then I see her hands slide down into her sleeping bag. She closes her eyes briefly and exhales sharply.

I follow her lead and govern my hands to the apex of my thighs. Normally I would have my eyes closed, but I need them open, watching her. I see her rhythmically moving under her sleeping bag, her jaw relaxing, her eyes fixed on me. Fuck she is sexy. I'd give anything to kiss her.

We move together against our sleeping bags, worlds apart but so in sync. I see her eyes close for a moment and I know she is close. She squints and opens her mouth, a small gasp escapes. I come just watching her.

She puts her forehead against mine and drifts off to sleep.

That morning I rise before Casey and get coffee going. She peeks out of the tent and sits by the fire, cute as ever.

We chat and giggle and flirt, same as always. She doesn't mention the night before and I decide that's probably best. Let's put this behind us. But...her smile. Look at that. Goddammit. I'm a sucker for a beautiful smile.

She leaves after breakfast and kisses me goodbye on the cheek. Innocent enough. Maybe we can just move past this and continue to be partners in saving lives. But...I do wonder what it would be like. Maybe it wouldn't be so bad? I'll bet Mark is nice. Wait...stop! This is so confusing!

I spend the rest of my camping trip communing with nature and doing yoga, making peaceful notions, and chilling in the sunshine. Fruitful trip if I do say so myself. I'm back at work on Tuesday, so I decide to take some time for some self care. I pop open a bottle of wine and turn on the tv after I get everything put away at home. Im on my second glass of wine when my phone dings. It's Casey.

"Hey! Just making sure you made it home. Work has been a shit show. Heads up." She texts.

"I'm working tomorrow. Thanks for the warning." I text back.

"Okay, see you tomorrow." She responds. Cool. Maybe it'll all be back to normal.

I get to work at 7am and there's already every room full. There's a 50 year old guy having a heart attack in the trauma room and a GI bleed that needs a blood transfusion. Pitter patter. Gotta get moving. Rest and relaxation be damned. We are back in the real world now. I get my patients stable and settled and start my documentation. This is going to take a while.

Casey has just come on shift at 9 and she stops by to say hi. She gives me an awkward smile and says she'll see me later. Honestly that's all I've got time for right now. People are having their worst day around me right now and I have to help.

My 12 hour shift ends at 7pm and I am spent. This has been a rough shift. I had a trauma patient die and another patient that doesn't look good. I did help some, but days like today take a toll. I need a stiff drink. Thank goodness I have tomorrow off.

I head to the stairwell where the time clock is and spot Casey.

"Getting off early?" I say.

"Yeah. It's administrations way of saving a buck, I guess." She says. "Listen, I wanted to make sure you are okay." She said.

"Oh, of course! We are good. I'm just fine." I say nodding my head.

"Good." She says, almost lightly, almost...disappointed..."I was thinking about you." She said. Oh no. My heart started racing the moment she said this, doubled by the fact that she was looking me dead in the face. Studying me. Just then she reached her hands up to my neck and brought my face to hers and kissed my lips lightly.

Lips barely touching, I feel the heat of her breath as she breathes out slightly. I back away, she smiles. I'm surprised. I bite my lip and she smiles bigger. Her grin lights up her whole face, and it makes my heart hurt. She's so beautiful. She kissed me. Wow.

"I..." I try to stumble through a word, not even sure what I want to say. She makes my head swim and I think she knows it. Do I do the same to her? I know my cheeks are red. I dip my head. She comes close to me and lightly touches the back of my hand with her fingertips, then trails them up my arm. I shiver and my heart is pounding.

"Just be in this moment with me." She whispers, bringing her lips to mine again. Everything around us is a blur. No sounds. No lights. All I can experience is this and it is overwhelming.

I bring my hands to her neck and stroke gently. I gaze into her brown eyes as she studies my face. She brings her hands to my hips and pulls me close. She wants me to kiss her back.

She whispers in my ear as she takes my hands and places them around her waist. "I want you to."

I kiss her hard and finally resign myself to what I know this means. Casey...and Mark.

I relish this moment, as I know this will be one of the only times she and I will be alone in this intimacy. I want to take her here and make her see god. But I can't. I have to meet Mark first.

"Take me home with you." I say to her, breathless.

She puts her forehead to mine and takes my hand. "Are you sure?" She asks. I kiss her to reassure her.

Casey leads in her car as I panic in my own and follow her to her house. What the fuck am I doing? This is wrong! Is he expecting you to fuck him? What if something happens you don't like?

Casey pulls into her drive next to a Chevy Silverado. Mark drives a black Chevy Silverado. What does this mean about him? Small penis? Probably.

She gets out and waits for me. I breathe deep and get out of my car. If ever there were a fairy godmother to keep me out of trouble, I need you right about now.

"Come in!" Casey says, opening the front door. The house is nice. Hardwood floors, country chic decor, and it smells like citrus. Like Casey. It's nice.

"Mark is excited to meet you. What do you want to drink? Wine?" She says and starts toward the kitchen. I follow mindlessly while surveying my surroundings.

I take a glass of what I determine to be Riesling and take a big, big drink. Just then I hear a mans voice coming from the garage.

"Hey, baby!" The man says as he comes through the door and takes Casey by the waist, planting a big kiss on her lips. Not going to lie, I felt a little jealous. Intimidated maybe.

He turned to me. "Hey, you must be Melanie!" He said, extending his hand. I shook it and obliged his greeting. "I see you have a drink. Can I get you anything?"

"I'm good, thanks." I say. My initial survey of Mark says that he is friendly. He is also young, 30ish, with a beard stubble and muscular physique. He definitely works out. He smells good, too. Not like Casey, but like sawdust. It's a tantalizing smell.

Mark must have picked up in my over analyzing. "Why don't we go out on the patio and have a drink." He says.

We all make our way outside where the air is crisp and the trees are vibrating with the evening air. I see why he picked this spot. It's freeing, and doesn't feel like I'm trapped at all. Smart.

Casey lights a joint and puffs, then passes it to me. I take it, hit it once, then pass it to Mark.

"Look, Mel, I know you don't know me." Mark starts. "I recycle, I vote, I donate to charity, I'm an avid runner and weightlifter (obvious from his physique) and I absolutely love this girl." He goes on. "Casey is the love of my life and I will do anything...anything to make her happy. So, I assume she has talked with you about our arrangement?" He seems so sincere and at ease with this.

"I've heard the gist." I say.

"Okay. So, I just want to reassure you that nothing will happen that you don't want. Nothing. If you ever feel uncomfortable just say the word." He says. "I want to make you both happy."

"I get it." I say. "It's not something I'm used to, but I'm willing to try."

"Nice." Mark says, taking a hit from the joint. "No pressure." He says laying his head back and passing Casey the joint. "Let's just enjoy tonight, then."

"Amen." Said Casey, shaking her head and smiling at me. Then she slipped over to me and kissed me. It happened so fast I barely realized it was happening until she was in my lap. She had her hands in my hair, tongue in my mouth, and she was riding my knee.

"Ahem." I hear. "Ladies, would you like to go inside?" Says Mark, holding a bottle of wine.

Casey stopped and smiled. "I want you to fuck me." She whispered in my ear. I get up and follow them through the house to their room.

Their room.

This is where Casey sleeps...with Mark. And he seems nice enough. Will he wear a condom? Does he have any diseases? How many times have they done this? I really haven't thought this through.

We get to their bedroom, and as I look around it seems perfectly normal. A king size bed with a big country style headboard. Blue gray walls, a master bath that seems nice with a big glass shower. White sheets. I decide if this is going to be my first time doing something like this, I'm going to call the shots.

"Mark," I say, matter of factly. "I need a shower. I just got off a 12 hour shift. Also, I expect you to wear a condom. I also expect that you do not touch me unless I specifically say it is okay. I think Casey is extraordinary, but I won't have my body disrespected."

Mark and Casey both look at each other, then me and smile. "Sounds perfectly reasonable." Mark says.

"Good." I say as I walk over to the shower and turn it on. "Casey, want to join me?"

She takes Mark's hands and they look at each other briefly. He kisses her cheek and then she walks to me, taking off her scrub top. We undress and enter the shower. As the steam fogs the glass I feel more empowered to handle Casey the way I naturally would. Knowing that Mark is just outside the shower is disconcerting.

Casey does her best to ease my apprehension. She takes my head in her hands and kisses me tenderly. She brings us both against the tile wall and I lift her legs, holding her close to me. She is so beautiful, so exciting, so new. I kiss her wet lips and savor the way the warm water makes her body feel against mine.

I can do this. I could do anything for her. Just to feel her come. I'd do anything to make her feel good. While she kisses me I hear the water turn off. I guess our time together is over.

Casey opens the glass shower door and reaches for a towel. She hands one to me and continues kissing me, helping me dry off.

"Come on. I promise you'll have a good time." She says, feeling my nervousness. "Just say the word and everything stops. You are in charge here."

"I just want you." I say as I kiss her lightly. She smiles.

We three gather at the foot of the bed. Mark unexpectedly takes a seat in a chair near the corner. Okay. Maybe this can be more like a normal date. I kiss Casey in her toweled garb, both of us a little damp from the shower. The kisses are my favorite. She and I just stand there, gently removing towels and lightly kissing each other's lips. It's innocent and a nice starting point for what I am apprehensive about.

Casey is naked now and sits on the bed. I follow suit and stalk her movements with my own. I'm on top of her, savoring her beautiful tan body and taking in the moans that are just for me.

As Casey and I are in the throws of enjoying what each offers I hear the rustle of clothing behind me. It's Mark taking off his shirt. I look back and see him, his abs, his shoulder tattoo, those muscles right above where the pants hit the hips. For a man, he is attractive. Casey sees my reaction to Mark and steadies my face in her hands "it's okay. He's fucking hot, right?!" She smiles. I'm not usually into guys, but Mark looks like an Abercrombie model. If I have to go there it might as well be with that.

Both Casey and I lay and watch as Mark unbuttons his pants. He smiles at us and drops them. He's wearing boxer briefs and, from what I can tell, he's fairly well endowed. He takes a foil wrapper from the drawer, puts it to his teeth, and opens it. He looks at us again and then drops his boxer briefs to reveal himself. He is hard, thick and about 8 inches. He places the condom on his uncircumcised tip and rolls it down.

Casey looks at me hard and kisses me. "Just say what you want or don't want." She says. Mark sits on the end of the bed and touches Casey's leg.

Casey sits up, motioning Mark to come near. Mark and Casey kiss. It seems natural, like they've done that hundreds of times. I guess they have.

Casey breaks from the kiss and looks at me. She wants me to kiss her...and Mark.

I sit up and touch Casey's face, trailing my fingertips down her neck. Mark watches intently. I tenderly kiss Casey and touch her breasts.

Mark touches Casey's stomach as I kiss her neck. I'm not sure why, but I reach my hand out and touched Mark's chest. It was hard and muscular, like I expected, but smoother than anticipated. Maybe it was curiosity, or maybe it was just the moment, but I needed to feel him. His heart. I wanted to know where his head was.

I found my answer. His heart was beating so fast. Just as fast as Casey's. He took this single touch as an invitation. He reached out and stroked my back with his strong hands. In this moment I knew I could trust him. I was safe with Casey and Mark.

The three of us kissed and caressed. Casey was to my right and Mark to my left. Mark rubbed and played with us both. Casey and I focused more on kissing, touching, the feeling of our bodies intertwined.

Mark sat up on his knees and asked for Casey. She went to him and kissed him. I instinctively wanted to join, so I went for his penis and put it in my mouth. His head arched back and Casey met me there and started mouthing his testicles, looking at me playfully.

"Melanie..." Mark asked, my mouth still wrapped around his dick. "Can I fuck you?"

"Lay down." I said to him. He obliges and I straddle him. I insert him as Casey kisses me.

Casey sits toward me, reverse cowgirl on Mark's face as I ride him. She kisses me and we find a rhythm together. Mark comes and Casey is close. I take her down to the bed, just me and her. Mark has gone to sit in a chair and watch more.

I put my mouth on the apex of Casey's thighs and she cries out. Between the "oh god" and the "yes yes" she shivers and shakes. I feel her release and see the glistening sweat on her chest and neck. Fuck she is beautiful.

She twirls us over and kisses me hard. Her fingers begin an assault that I can only describe as otherworldly. Fuck. Yes. Yes. Yes. At one point I hear Casey say "dirty slut." Playfully. I come so hard after that. Wow. Just... wow.

The remainder of the night Mark sat nearby, just watching, smiling, and enjoying the show. Casey and I were insatiable. She and I made love so many times, and when Mark finally passed out in the chair we went back to the shower.

She and I up against the tile, her legs wrapped around me, my fingers inside her and her crying out in pleasure. This will always be one of my favorite memories.

I woke the next morning with a cup of coffee and a note from Casey. "Gotta get to work. Text you later 3"

I got my bearings and sat up to drink my coffee. It was warm, so she hadn't been gone long. Where was Mark?

"G'mornin beautiful!" I hear Mark coming in from the bathroom.

"Hey there, stud." I say. Half joking.

"Ah...someone had a good time last night." He said jokingly.

"You?" I said smiling, remembering that I am completely naked under the sheets.

"Well, yes actually. And hopefully you, too. I'd love to do that again sometime." He said as politely as he could. What a sweetie. "Want some wine? A little hair of the dog for your hangover?"

"Yes, actually. Thanks." He poured us two and I sat up to drink mine as he sat next to me on the bed.

"Well...did you have a nice time? I mean... was I..." he asked sweetly.

I smiled, "you were great. I'm not usually into men, but you were definitely an exception. Very gentle, very sexy." I said.

"Thank you. That's nice to hear." He said, almost whispering. "You are so...so beautiful." He said quietly. Just then he looked up at me. His brown eyes hungry. He brought his fingertips up to my jaw and traced down to my collarbone, shoulder, arm, wrist. I shuddered remembering the night before and his girth satisfying me.

He slowly brought his lips to mine. I kissed him back for a moment, then stopped. "I can't." I said.

"Mmm" he said, moving to my neck, obviously excited. "Shhh, cmon. I know you want me." He whispered. He was on top of me, moving the sheets back. I needed to stop him from getting more excited.

"No, Mark. We can't do this." I say, tilting my head away from his kisses. He continued and as I tried to wriggle free he took both of my hands in his. He reached his right hand down and unbuttoned his pants and zipper. I felt him hard against my thigh and once again protested against his assault of kisses. "What about Casey?"

"it'll be our little secret." He whispered in my ear. I felt him enter me and he kissed me at the same time. He's so big. He bit my earlobe and circled his motions and it felt divine.

"Harder." Is the only thing I could say. If I was going to fuck a guy, I wanted it to be worth it. He delivered as best he could. He was in great shape so he was able to fuck me hard, fast, and for a while. He had me up against a bookcase, on the dining table, and on the couch where we finally finished. I came hard, but he was spent. Poor fella. Girls are still better. More passion, less machismo.

After that I decided it best to leave while I had a chance. On the way home I went over the night and morning. Had I fucked up? I just screwed Casey's boyfriend. I wanted her, but I had sex with a guy. Why? I didn't even like guys. I feel like I'm taking crazy pills. What the fuck? I need some time to think. I turn off my phone and get home and straight into the bath.

I fill it up with super hot water and bubbles, ready for a long soak. Just as I am about to get in there's a knock at my door. I wrap a towel around me and head downstairs. Through the peephole I see Casey. Fuck.

I open the door "hey" I smile. "Thought you were working today."

"I was covering Meredith for a few hours so she could take her kid to the dentist." She said. "Nice place."

"Thanks. Come on in. Make yourself at home." I say.

"The...towel." She says, pointing at my ensemble.

"I was just about to take a bath."

She smiles, "can I join you?" Oh man. I need to tell her the truth.

"Casey, after you left this morning Mark and I had sex,"

Casey stood there, still.

"Wait, what?!" She said. She yelled.

"I'm sorry. I do not play games. I needed you to know." I said, tearing up.

Casey stills, then started laughing. "I know! Mark and I are besties. We tell each other everything. The fact that you don't play games is what we love about you."

Well color me surprised. Okay. This could be good.

"In that case, have you ever experimented with bondage?"

Casey's eyebrows raise and she looks intrigued.
